Thanks that makes perfect sense. If what you say is true, and I am sure it is, we get it. The articles out there on the subject were confusing at best and while we are computer and imaging experts our knowledge of color spaces is not nearly as complete.

We always knew the picture styles settings applied only to JPEG but we had no idea the color space did too. Now it all makes sense.

We have started using Prophoto on all our iMacs, so perhaps we'll look into running it on our workstations as well.
